a higher level of success. anesthesiologists at the university hospital had developed a new device for monitoring anesthesia the risk of waking up during an operation is particularly high when drugs are administered intravenously. one possible reason for this is that propofol concentration in the body cannot be measured yet. but in inhalation anesthetics the so-called blood gas partition coefficient describes this. and the fact that the concentration of volatile anesthetics can be measured a measure of the concentration which i didn t have until now with profile which is why the probability of over and under dosing is higher than with cas anesthetics. this new device is intended to remedy the situation the edmund measures the
a few seconds. the last step is muscle relaxants substances that relax muscles and immobilize the patient. without these the body s protective reflexes could cause involuntary twitching even while under. under that you please. and press. patients would suffocate without artificial ventilation. once anesthesia has been induced patients must be kept under. as just an tissues prone to nausea she s receiving propofol as this causes nausea less frequently than volatile gaseous anesthetics. protocol can have other side effects such as drops in blood pressure or apnea. just in tissues now unresponsive.
anesthetics. it puts hardly any strain on circulation. the effect begins quickly and also disappears quickly so that patients regain alertness soon after surgery. but on this the internet is these the ologist wants to end the anesthesia that they can make a patient up very quickly this is the fastest drug we have and that is these are in terms of coronary flow dynamics the affected. as on blood pressure is very stable and patient s blood pressure remains approximately what it was at the beginning which is much better for them and. coburn was researching how well elderly patients recovered after hip surgery he found that xenon anesthesia leads to significantly less complications and mortality is also lower. seen on has been approved as an anesthetic gas since 2005.
responsible for a patient losing consciousness is not yet clear. and most likely also depends on the ennis that accused. there are anesthetics that do not act on the messenger but on the other neurotransmitters. to make it researchers are investigating these differences with a micro e.g. that measures signal transmission in the mini brains neurons. so far all anesthetic drugs have been found by trial and error doctors know that they work but not exactly how they work. however understanding the how is an important prerequisite for reducing side effects. we should really be looking at patients individual needs and attributes and choosing the substances they get accordingly we need a rational approach and not just a trial and error approach to see if it works and if it does that s good enough.
a single how can that me. we have identified proteins that are absolutely essential for anaesthesia but identifying these small building blocks alone doesn t come close to explaining how consciousness is lost and from the get. the researchers are using mouse brains to try to better understand how different substances used in anesthesia work. for many decades scientists thought all anesthetics essentially blocked information from reaching neurons by causing a malfunction and their lippitt membranes. however this limpid theory has since been abandoned today researchers know that every anesthetic has a different way of causing a consciousness of. brain tissue cultures taken from areas of the brain involved in loss of consciousness are put into a nutrient solution for several weeks during which time they grow into many brains which can be used for experiments. this is what researchers have
